Tuck suffered an undisclosed injury, and with the short timeframe, UFC officials won’t search for a replacement, sources close to the event confirmed with MMAjunkie.com (www.mmajunkie.com).

UFC on FOX 7 takes place at HP Pavilion in San Jose, Calif. The main card airs on FOX following prelims on FX and Facebook.

Parke vs. Tuck was slated for the FX-televised portion of the card. A substitute bout from the Facebook prelims likely will be promoted.

Parke was slated to fight for the first time since December, when he defeated Colin Fletcher to win “TUF.” It was his seventh consecutive victory. Tuck, meanwhile, made his UFC debut in November and defeated Tiequan Zhang, which also marked his seventh straight win.
